Title: Absorptiometer
Inventor: YASUNAKA TOSHIO
IPC: G01N21/59
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To lightly and stably perform measurement even in the light by measuring absorbancy on the basis of electrical electronical modulation in the predetermined frequency of LED light. SOLUTION: A sample soln. is continuously allowed to flow through a tube 1 and a start key is operated to start measurement. An LED 32 flickers in frequency of 20kHz corresponding to the oscillation signal of an oscillation circuit 21 and a part of the light thereof is absorbed by the sample in the tube 1 and only transmitted light arrives at a photodiode 34 along with external light. Only a component with frequency of 20kHz in the detected luminous intensity of the arrival light passes through a BPF 23. The external light component from solar rays or a fluorescent lamp is removed because frequency is different. Then, absorbancy is calculated on the basis of the luminous intensity only of transmitted light. Even if the circumference is bright or dark and light and shade changes, absorbancy can be stably calculated.

Title: Sputter film, liquid crystal element and their production
Inventor: SAWAMURA MITSUHARU
IPC: C23C14/44
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To prevent damage of a target and substrate by an abnormal electric discharge and to obtain sputter films and more particularly transparent conductive films of ITO, etc., having good film quality without receiving the influence of the gases generated from the substrate by impressing VHF high-frequency electric power to the target in the sputtering chamber of a single-substrate type sputtering apparatus and executing sputtering. SOLUTION: The sputtering is executed by impressing the VHF highfrequency electric power having frequencies of a VHF band on the target in the sputtering chamber. As a result, the films are hardly subjected to the damage of ions when the deposition is executed by, for example, a magnetron sputtering method. Further, the temp. rise of the substrate surface by the inflow of electrons is suppressed and the generation of the gases from the substrate is suppressed. The enhancement of the resistance of the sputter film and the degradation in the transmittance thereof by the gases are suppressed. On the other hand, the sputtering with a low voltage is made possible by the lowered target impedance. The charge-up quantity of the target surface is decreased by the drop of the target voltage, by which the abnormal electric discharge is prevented and the damage of the target is prevented.
